Enchanter is #1 solo class? What is this madness

[Sillyturtle]

Ok so clickbaity title aside, I was always taught that Shaman with Torpor was the king of soloing tough mobs and farming high end gear. Then I read that it's actually Enchanter.

How so?

I did some research and learned about their ability to slow mobs, and of course their pet is very strong. But how do they deal with losing health?
